Abstract

Transponder system comprising an interrogating device (BOA) and at least one responding device (TAG) in a bi-directional cable-less communication, where the interrogating device (BOA) and the at least one responding device (TAG) are provided with means for communicating through two distinct transmission channels, one channel for the activation, by the interrogating device (BOA), of a responding device (TAG) present in a preset activation area (MFP), the other channel, bi-directional, for data exchanging between the interrogating device (BOA) and a responding device (TAG) positioned within a data exchange area (RFP). <IMAGE>
